WHAT ARE 4 WAYS TO IMPROVE PERCEPTION
– Authentic Communication
– Empathy
– Positive Attitude
– Cultural Influences
WAYS TO IMPROVE PERCEPTION
_________ - Becomes very important as communication has to be proper and effective and needs to be understood by others in the way you wish it to be understood.
Authentic Communication
WAYS TO IMPROVE PERCEPTION
________ - it helps to understand the situation by keeping oneself in the shoes of others.
Empathy
WAYS TO IMPROVE PERCEPTION
keeping a __________ also helps in improving the perception. For example, consider an
employee who is not performing up to the expectations of the superiors and has since been a
consistent failure, however, by keeping a positive attitude, he/she can take effective control of situation, thus preventing one’s perception to
get distorted.
positive attitude
WAYS TO IMPROVE PERCEPTION
_______ - an individual’s upbringing to an extent guides one’s perception. Though it may be difficult for an
individual to change one’s perception, yet one should try to be flexible and accommodating enough to be able to shape up one’s perception.
Cultural Influences
Types OF PERCEPTUAL ERRORS
▪ an individual is perceived based on a single trait.
▪ a single trait may cast its influence on all other traits
Halo Effect
Example: A person may have done some good work, some time ago which was highly appreciated by his boss. This deed by the individual might have touched the boss to such an extent that all other qualities, be it negative, get overshadowed by just one good deed of the individual. Such an error often finds its way in the performance appraisal exercise wherein the rater tends to rate an individual very high or very low based on a single trait, thus permitting a high degree of bias to creep into the appraisal.
Types OF PERCEPTUAL ERRORS
▪ may disrupt the perceptual process
▪ in its simplest sense would mean “typecast”
Stereotype
Example: A teacher may stereotype that ‘back benchers are laggards’ or a boss may typecast that ‘athletes make up good salesmen’. Such types of generalized statements may influence the interview process for instance and may bias the interview ratings.
What are 3 types OF PERCEPTUAL ERRORS?
– Halo Effect
– Stereotype
– Projection
Types OF PERCEPTUAL ERRORS
▪ often creeps in due to incorrect perception of an individual
▪ seen during interviews that when the panelists are taking the interview of a candidate, it is very likely that one or more panelists may see their projection in the candidate or in other words their likes or dislikes may be the same as that of the candidate and hence their interview ratings could get biased
Projection
Example: While probing the personality of a candidate, the interviewer may ask about the hobbies of the candidate, to which the candidate may respond with an answer which conveys a set of hobbies that is like one or more of the panelist. In such a situation, the interviewer is likely to see his personality in the candidate which may compel him to skew the rating.
